Excluded Species 1041 



184. Morus nigra L. Black Mulberry. There are three reports of 

 this species as a native tree and of course all are wrong determinations. 

 I have planted the species twice at Bluffton and it is only semi-hardy. 



Nat. of w. Asia. 



185. Papyrius papyrifera (L.) Kuntze. {Broussonetia papyrifera 

 (L.) Vent, of Gray, Man., ed. 7.) Paper-mulberry. Reported as an escape 

 in Gibson County. I had a specimen, purporting to be this species sent to 

 me from Vanderburgh County and it proved to be the Russian mulberry. 

 This is a small round-headed tree often planted in lawns and along streets 

 in Evansville, Mt. Vernon, and New Harmony where it has proven to be 

 hardy but we have no evidence that it has escaped. 



China and Japan. 



186. Ficus Carica L. Common Fig. I found several shoots, 3-6 feet 

 high, of this species in 1918 along the Southern Railroad in Gibson County. 

 The plant was visited a few years later and it still persisted. It was again 

 visited and it had disappeared. In 1932 Chas. 0. McBride, of Bedford, 

 sent me a specimen which he said was from a clump growing on the top 

 of a pile of stones. He adds : "It does not seem to be hardy in this loca- 

 tion." The determination of this specimen was made by Alfred Render 

 of the Arnold Arboretum. It is reported to be hardy as far north as 

 Tennessee. 



Nat. of Asia. 



187. Humulus Lupulus L. Common Hop. This species has been re- 

 ported from 23 counties. I believe all of these reports should be referred 

 to our native species and I am excluding the introduced species from our 

 flora because I have not seen a specimen. Our native species is not recog- 

 nized by our manuals although the differences seem to me to be convincing. 



Eurasia. 



188. Comandra umbellata (L.) Nutt. Bastard Toadflax. There 

 have been 30 reports of this species from 20 counties. According to Fernald, 

 its range is east of the Allegheny Mountains which means that all of our 

 reports should be referred to Comandra Richardsiana. 



Cent. Maine, southw. to Ga. 



189. Geocaulon LiviDUM (Richardson) Fern. (Rhodora 30: 23-24. 

 1928.) (Comandra livida Richardson of Gray, Man., ed. 7 and Britton and 

 Brown, Illus. Flora, ed. 2.) This plant was reported from Marshall County 

 by Clark. Since the range of this species is north of Indiana I assume that 

 Clark made an error in determination. 



Lab. to Alaska, southw. to s. N. B., e. Maine, mts. of N. E., n. Mich., 

 Sask., Alberta, and B. C. 



190. Rumex conglomerates Murray. This species was reported from 

 Jefferson County by Barnes. Since we have no specimen and the species 

 does not belong to our area, I exclude it. A specimen in the herbarium of 

 Wabash College collected by J. M. Coulter in Jefferson County is Rumex 

 obtnsifolius. 



Va. to S. C. ; also in Calif, and Wash.
